Novel quantum dot and nano-sheet TiO2 (B) composite for enhanced photocatalytic H2 – Production without Co-Catalyst

Recent advances in syntheses, properties and applications of TiO2nanostructures

“…For H 2 production, a remarkably higher photocatalytic activity was compared to frequently used Pt/TiO 2 . Si et al 255 synthesized anatase TiO 2 , thin TiO 2 (B) nano-sheets and their composites. The properly aligned structure of band, with the conduction band level of ultra-thin TiO 2 (B) was about 0.6 eV higher than that of the anatase.…”

Interface-Driven Multifunctionality in Two-Dimensional TiO2 Nanosheet/Poly(Dimercaptothiadiazole-Triazine) Hybrid Resistive Random Access Memory Device

“…The known band gap value of bulk TiO 2 is ∼3.2 eV, but the previous reports and our experimental observations (see the Supporting Information Figure S1a) suggest that the band gap of 2D TiO 2 -NS is found to be ∼3.53−3.6 eV, which might be due to the quantum confinement effect. 32,34 The band gap of poly(DMcT-CC) (∼3.04 eV) thin films coated on FTO was obtained from the Tauc plot of UV absorption spectra and shown in Supporting Figure S1b. The HOMO and LUMO levels of the Poly(DMcT-CC) are calculated to be about −3.74 and −6.8 eV, respectively from the UPS spectra (see Supporting Information Figure S1c for further information).…”

M/TiO2 (M = Fe, Co, Ni, Cu, Zn) catalysts for photocatalytic hydrogen production under UV and visible light irradiation

“…This allows the injection of photogenerated electrons from the conduction band of the semiconductor into the metal. 29 Up to now few studies on the use of non-noble metals as cocatalysts have been reported [30][31][32][33] To analyse the photocatalytic behaviour of the prepared M/TiO 2 photocatalysts (M= Fe, Co, Ni, Cu, Zn) under both visible and UV light irradiation, TiO 2 was loaded with 2 wt% of selected transition metals. Hydrogen production profiles for TiO 2 impregnated catalysts are shown in Fig.…”
